Abstract
A user authentication apparatus trains a user authentication model by using biometric data of a user which was used in previous user authentication as training data, and performs user authentication by using the trained user authentication model.
Claims11
A method of performing user authentication, the method comprising:
- obtaining biometric data;
- performing user authentication based on the biometric data;
- adding the biometric data to training data after the performing the user authentication;
- training, by using the training data, a user authentication model that is a machine learning model configured to perform the user authentication;
- and
- performing the user authentication based on new biometric data by using the user authentication model,
- wherein the adding comprises:
- adding success biometric data to the training data, the success biometric data being the biometric data that succeeded in the user authentication;
- and
- adding previous biometric data to the training data, and
- wherein the adding of the previous biometric data to the training data comprises adding a predetermined number of pieces of the previous biometric data obtained within a predetermined period before the success biometric data is obtained to the training data.
8 more elements
An apparatus for performing user authentication, the apparatus comprising:
- a sensor configured to obtain biometric data;
- a memory configured to store at least one program;
- and
- a controller configured to perform user authentication by executing the at least one program,
- wherein the at least one program comprises instructions to implement operations of:
- performing the user authentication based on the obtained biometric data;
- adding the biometric data to training data after performing the user authentication;
- training, by using the training data, a user authentication model that is a machine learning model configured to perform the user authentication;
- and
- performing the user authentication based on new biometric data by using the user authentication model,
- wherein the adding comprises:
- adding success biometric data to the training data, the success biometric data being the biometric data that succeeded in the user authentication;
- and
- adding previous biometric data to the training data, and
- wherein the adding of the previous biometric data to the training data comprises adding a predetermined number of pieces of the previous biometric data obtained within a predetermined period before the success biometric data is obtained to the training data.
